  1. Tom O'Leary says:


    Confuse the wicked, O Lord. Confound their speech, for I see violence and strife in the city.
    Day and night they prowl about on its walls; malice and abuse are within it.
    Destructive forces are at work in the city; threats and lies never leave its streets.
    (Ps 55:9-11)

    Be careful out there!
